IMPROVEMENT IN SPINNING-MACHINES.

Specification forming part of Letters Patent No. 203,632, dated May 14,1878; application filed November 12, 1877.

To all whom it may concern.-

Be it known that I, JAMES B. MACKIE, of the city and State of New York,have invented an Improvement in Spinning-Machines, of which thefollowing is a specification:

In spinning-machinery it is usual to have two ranges of bobbins, one ateach side of the machine, driven by separate belts, with the drawing orwinding rollers above. These machines occupy considerable space. and theclothes of the attendant are liable to get caught in the belts orpulleys.

The object of my invention is to render the spinning-machine morecompact and easily managed by dispensing with one set of driving-pulleysand driving two ranges of spindles by one range of shafting and pulleys.ThlS dispenses with the cost, weight, and friction of a second shaft andrange of drivingwheels; hence I116 construction and maintainan ce areless expensive than in other machines for this purpose, as considerablefriction is avoided.

In the drawing, Figure l is a vertical section representing the spindlesand their driving mechanism; and Fig. 2 is a side view, showing aportion of the range of spindles.

The spindles a rest with their lower ends within the bearings b, andeach spindle is provided with a friction-pinion, c, of a conical orother suitable shape, driven by contact with the edge or rim of thewheel d, the parts being of usual character, and reference is made toLetters Patent N 0. 179,496, in which a similar manner of driving asingle spindle is illus trated.

I arrange the shaft a. of the driving-wheels d in the center of themachine transversely, or nearly so, and run said shaft longitudinally ofthe machine, and place upon the same the friction-wheels d at suitabledistances apart to correspond with the distances that the spindles'areapart in each row. Insteadof having a shaft, a, and row of wheels d foreach row of spindles, I make use of the shaft a and the one row ofwheels d upon the shaft a, and I introduce two rows of spindles at aninclination to each other, and radially, or nearly so, to thedriving-wheels, as shown in Fig. 1, so that one row is at the properdistance from the other, and both are above the driving-wheels, so thatthe threads can be led off to the drawing or winding rollers.

I remark that in the winding of silk the threads or fibers are usuallydrawn oil the bobbins and wound together on spools as they are twistedby the revolution of the bobbins, and in drawing and spinning machinerythe threads will be spun and wound upon the bobbins as they aredelivered by the drawingrollers. I

The bearings 12 for the spindle are connected by arms to separate barsh, one at each side of the shaft a, forming part of the frame of themachine; or such bearings may be supported by a central bar, as shown bydotted lines in Fig. 1. The frictional pinion of each spindle is kept incontact with its wheel by a yielding presser composed of the spring-armcarrying the bearing, as in aforesaid patent, or in any other desiredmanner.

By this improvement the spinning-machine is simplified. One shaft andits wheels drive two ranges of spindles. The spindles are adjacent toeach other but the bobbins are applied or removed at the respectivesides of the machine, and there are not any belts to become broken orinefficient, and great uniformity of twist is obtained.

I am aware that spindles have been driven by friction-belts, and thatfrictional gearing has been employed in driving spindles. In someinstances. a horizontal wheel has been used to drive two verticalspindles. By my arrangement the gearing is simplified and thespinning-machine rendered much more compact than the machines beforemade.

I claim as my invention- In a spinning machine, the longitudinal shafta, in the center, or nearly so, transversly of the machine, and providedwith a beveled friction-wheel, d, for each pair of spindles, incombination with spindles and their beveled friction-pinions, arrangedin the manner shown, so that there are two spindles to each beveledfrictional driving wheel, and said spindles stand radially above thesame, as and for the purposes set forth.

Signed by me this 9th day of November, A. I

JAMES B. MAOKIE.
